SPECIFICATION forming part of Letters Patent NQ 385,696, dated Juif; 10, 1888.

Application filed September Q1, 18S?. Serial No. 250.325. (No model.)

To all whom, it may concern:

Beit known that l, JOI-IN C. COLE, a citizen ofthe United States, residing at Brcnts, in the county of Lincoln, Vashington Territory, have invented new and useful Improvements iu Churns, of which the following is a specification.

My invention relates to improvements in churns; and it consists in a certain novel construction and arrangement of parts, fully set forth hereinafter, and specilically pointed out in the claims.

In the accompanying drawings, Figure 1 is aside elevation of the device, with the churnbody shown in section. Fig. 2 is a section on the line x of Fig. l. Fig. 3 is a detached detail View of the joint between the revolving sleeve and the outer dasher. Fig. 4 is a hori- Zontal section through the said joint 011 line y y of Fig. 3. Fig. 5 is a detail view showing the manner of coupling the upper bars of the dashers. Fig. 6 is an enlarged detail view of the lower ends of the dashers.

Referring by letter to the drawings, A designates the body of the churn, provided on the inside with vertical ribs a a, to serve as breakers for the contents of the body.

C designates the lid of the churn, which is fitted in the upper end ofthe body, and may be secured in place in any desired manner.

D designates a standard or yoke arranged on the upper side of the lid, in which is journaled the operating mechanism of the churn.

E designates a vertical rod, secured at its upper end in the upper side of the standard D, and at thelower end in thelid of the churn, and the said rod is provided at its upper and lower ends, respectively, with gear-wheels F F. The wheel F is provided on the lower side with the small bevel gear-wheelf, which is rigid with the gear F, and the gear F is provided on the upper side with the bevel gear-wheelj", which is rigid therewith.

G designates a shaft jourualed in the side ofthe standard, to the inner end of which is attached the bevel gear-wheel G', which is adapted to engage at opposite sides with the bevel gear-wheels f and f, and the opposite end of the said shaft is provided with a crank or a similar means by which power may be conveyed to the elmrn-dashers.

It will be understood that the gear-wheels F and F are journaled on the rod E, and when the gear-wheel G revolves the said gearwheels are rotated in opposite directions.

H designates a vertical shaft journaled at its upper end in the upper side of the standard l), and passing at the lower end loosely through an opening iu the lid. The upper end ol1 the shaft H is provided with a rigid gear-wheel, H, which mcsheswith the gearwheel F, the gear-wheel H being much smaller than the wheel F.

The opening I in the lid, through which the lower end of the shaft H passes, is much larger than the said shaft, and in the bearing thus formed is journaled the sleeve J, which sur-V rounds the shaft H near its lower end. The said sleeve extends above the lid: and is provided on its upper end with a gear-wheel, J', and the said sleeve extends below the lid, and is provided ou one side with a loop, j, which forms a groove communicating with the 1nterior of the sleeve. The shaft H extends a short distance below the lower end of the sleeve J, and is squared.

K designates the outer orlarger dasher, comprising the upper cross-bar, K', and the lower erossbar, K2, and the blades K3 K3, connecting the extremities of the said bars. The upper side of the cross-bar K is provided with a vertical sleeve, L, adapted to receive the lower end of the shaft H, and the said sleeve is provided ou one side with the rib Z, adapted to lit in the groove in loopj on one side of the sleeve J and prevent the sleeve L from turning independently of' the sleeve J. rlhus it will be seen that when the rib Z is engaged in the groove in loop j on the side of the sleeve J, if the sleeve J is rotated by means of the gear Wheel Ji', the outerdasher willalso be rotated; but at the same time the said dasher may be removed from engagement with the lower end of the sleeve J at any time. The lower side ofthe crossbar K, around the opening therein, is provided with a downwardlyecxtending 'flange or barrel, M, provided in one side with au opening, in, for a purpose hereinafter de scribed.

N designates the inner or smaller dasher, which comprises the upper crossbar, N, the lower cross-bar, N2,a1id theblades N3, secured at the ends to the extremities of the cross-bars. The upper cross-bar, N, is provided on the upperside with the upwardly vextending flange or barrel O, adapted to be passed intothe barrel M through the opening min theside thereof, and adapted also to rotate in the said barrel. The said barrel O on the upper side ofthe bar N surrounds the square opening o in the said bar, and also embraces the lower end of the shaft H, and the squared lower end ofthe shaft H ts in the square opening 0 and causes the inner dasher to rotate with the upper gearwheel, H', which is secured to the upper end of the shaft H. Thus it will be seen that if the gear-wheels F and F rotate in opposite directions the gear-wheels H' and J will also rotate in opposite directions, and consequently the dasher will rotate in opposite directions. The lower cross-bar, K2, of the outer dasher is provided on the lower side at the center with a depending pintle, k, adapted to be stepped and operate in the socket a in the center of the bottom of the body A, and the upper side of the said cross-har is provided directly over the pintle 7c with a socket, k. The lower side ofthe cross-bar I 2 of the inner dasher is provided with a depending pintle, a, adapted to bear and operate in the socket k', before mentioned.

The blades of the dashers are twisted outwardly at the upper ends, and the lower ends thereof are projected forward of the upper ends. The dasher-blades are also provided on the outer edges with flanges 7c" and n, respectively, which are adapted to draw the contents of the tub inwardly, while the twisting of the blades tends to throw said contents outwardly at the upper ends.

The construction of the device is simple and the operation thereof will be found very effective, causing butter to be separated very quickly and thoroughly.

It will be seen from the above description that the lid of the churn may be taken off, leaving the dashers in the body. This is pos.- sible because the lower squared end of the shaft H will slip out of the opening in the upper end of the dasher N, and the sleeve L will slip out of the sleeve J. It will also be seenthat when the dashers are detached from the operating mechanism they do not become separated, as the barrel on the upper side of the upper bar of the inner dasher is held in the barrel on the lower side of the upper bar of the outer dasher, while the spindle on the lower end of the inner dasher is engaged in the socket in the lower end of the outer dasher.

This construction enables the dashers to be freed from the operating mechanism, so that the former may be cleaned before being removed from the churn -body, while the operating mechanism may be removed and taken out of the way.

Having thus described my invention, I claim- 1. In a churn, the combination, with the body A, having a lid, of the standard D, se-

cured to the said lid, the rod E, secu red in the said standard and having the independentlymoving gear-wheels Fand F loosely mounted on the upper and lower ends thereof, respectively, the bevel gear-wheelsf and If', secured rigidly to the lower and upper sides of the gear-wheels F and F', respectively, shaft G, journaled in the side of the standard, and having the gear-wheel G' on its inner end engaging with the gear-wheels f and f at opposite sides, the vertical shaft H, journaled at its upper end in the upper side of the standard and at its lower end in a bearing in the lid, and having a gear-wheel rigidly secured to its upper end, and meshing with the gear-wheel F and the dasher on its lower end, the sleeve supported by the churn-lid and surrounding the lower end of the said vertical shaft, and having a gear-wheel on its upper end meshing with the gear-wheel E', and adasher connected to said sleeve and revolving around the dasher secured to the shaft H, all arranged and operated substantially as and for the purpose specified.

2.
